Bleeding the fuel system.
1. Ensure the fuel level in the tank is at a suitable level and the fuel switch on the
fuel filter bowl (behind the Raptair service panel) is in the on position (vertical).
2. Check and ensure that the fuel systems is sealed, that there are no fuel leaks, no
kinks in the lines and that there are no points where air can be drawn into the fuel
system.
3. Ensure that the electronic primer pump is installed as close as possible to
the tank (Maximum 2 meters from the tank). This is a pusher pump and not a
suction pump. The primer pump filter should be installed before the pump and
preferably vertically mounted.
4. Turn the Raptair key on the control panel to the first position (Do not continue to
the start position)
5. Listen to hear the primer pump is running.
6. At the fuel filter bowl, (Fig 4 [A]) loosen the inlet screw and allow fuel to flow out.
Use a cloth to catch the fuel surplus and allow flow to continue until there are no
further air bubbles coming out. Tighten the inlet screw. Next, loosen the outlet
screw and bleed until all air bubbles are gone. Tighten the outlet screw.
7. At the injector pump (Fig 4 [B]) locate the Fuel bleed screw on the side of the
pump, loosen the Fuel bleed screw and allow the fuel to flow out into a cloth and
again wait until the air bubbles are cleared then retighten the Fuel bleed screw.
8. Check the fuel bowl sight glass is full and proceed to start the Raptair. The Initial
start will be a little rough until internal pump and injector lines are cleared of air.
Run the Raptair until fully warmed.

Testing the External Fuel Pump
1. Turn the key from OFF to RUN, the fuel pump should activate.
2. Turn the key from RUN to OFF, the fuel pump should deactivate.
3. Turn the key to RUN and start the compressor system, the fuel pump should
activate and run the entire time.
4. Do not discharge air and wait until the unit enters STANDBY mode (engine
shutdown and LED beacon illuminates).
5. In STANDBY mode, the fuel pump should be deactivated.
6. Dump air to allow the system to restart, the fuel pump should reactivate.
7. Turn the system off and key switch to OFF.
Updating the System Settings
The fuel pump uses the beacon output for its control logic. When the beacon is turned on in standby
mode the fuel pump is disabled. If the DISABLE AUTO RESTART DELAY is reached then the beacon will
shut off, and the fuel pump will be enabled again, potentially damaging the pump if left running for an
extended period.
The update to the system setting will disable the delay setting used to shutoff the control system in
STANDBY mode. After this setting change, the unit will no longer disable automatic restart if left
unattended for the default 30minutes. Ensure the unit is switched off if left unattended for an extended
period of time.
Failure to change the settings may result in damage to the fuel
pump.
1. Turn the key from OFF to RUN.
2. In the Display box enter the Diagnostic settings and change DISABLE AUTO
RESTART DELAY to NEVER. Refer to the owner’s manual for details on
entering Diagnostics and setting values.
3. Confirm the value has been successfully updated to NEVER and exit
Diagnostics mode.
4. Turn the key switch to the OFF position.
